Toy

ABSTRACT

A toy includes a speaker, a control unit, and a PCB carrying the control unit. The toy defines a first cavity and a second cavity substantially isolated from each other. The first cavity receives the printed circuit board. The second cavity receives the speaker. The isolation of the first cavity and the second cavity increases a dB sound pressure level.

BACKGROUND

1. Technical Field

The disclosure relates to a toy, and particularly to a toy capable ofemitting sound.

2. General Background

Toys that emit sound are very important in today's market. To make thesetoys competitive in today's market, people are continuously improvingthe sound quality of the toys. However, improving the sound quality oftoys often means choosing more expensive sound components for the toys.As a result, the costs are often passed on to the consumers.

Thus, what is needed is a toy that can emit higher quality sound, butwithout more expensive sound components.

SUMMARY

A toy is disclosed. The toy includes a speaker, a control unit, and aprinted circuit board carrying the control unit. The toy defines a firstcavity and a second cavity substantially isolated from each other. Thefirst cavity receives the printed circuit board. The second cavityreceives the speaker.

Other advantages and novel features will become more apparent from thefollowing detailed description of embodiments when taken in conjunctionwith the accompanying drawings. The isolation of the first cavity andthe second cavity increases a dB sound pressure level.

DETAILED DESCRIPTION

Referring to FIG. 1, a human-figured toy 10 according to an exemplaryembodiment of the present disclosure is disclosed. The human-like toy 10includes a head 20, a torso 30 for supporting the head 20, two upperlimbs 40 and two lower limbs 50 connected with the torso 30.

Referring to FIGS. 2 and 3, the head 20 includes a top part 21, a middlepart 22, and a bottom part 25. The top part 21, the middle part 22 andthe bottom part 25 form a first cavity 27 when the top part 21, themiddle part 22 and the bottom part 25 are assembled together. The head20 further includes a neck 26 for connecting with the torso 30. The neck26 is attached, and extends out of the bottom part 25. The neck 26defines a through hole 261 communicating with the first cavity 27.

The first cavity 27 receives a printed circuit board (PCB) 24 and a nosedriving unit 23. The PCB 24 carries a control unit (not shown) forcontrolling the human-figured toy 10. The nose driving unit 23 includesan enclosure 230, a motor 231, and a nose 232. The motor 231 is mountedin the enclosure 230. A first end of the nose 232 cooperates with themotor 231. A second end of the nose 232, opposite to the first end,extends out from the bottom part 25. The motor 231 is controlled by thecontrol unit and drives the nose 232 to extend or retract.

Referring to FIGS. 4 and 5, the torso 30 includes a chest 31, a frame32, and a back 33. The frame 32 includes a first joint 321 forconnecting with the neck 26, two second joints 322 for connecting withthe two upper limbs 40, and two third joints 323 for connecting with thetwo lower limbs 50. The chest 31, the frame 32, and the back 33 form asecond cavity 34 when the chest 31, the frame 32, and the back 33 areassembled together. The first cavity 27 and the second cavity 34 arerespectively formed in the head 20 and in the torso 30, and onlycommunicate with each other by a through hole 261 of the neck 26. Thus,the first cavity 27 and the second cavity 34 are substantially isolatedfrom each other.

In the second cavity 34, an annular flange 310 is formed on an innersurface of the chest 31. A speaker 14 is attached to the flange 310. Abaffle 324 formed on the frame 32 lies against the speaker 14 forpreventing the speaker 14 from detaching from the flange 310. Thecontrol unit in the head 20 controls the speaker 14 to reproduce/outputsound, such as vocal sound, via a wire (not shown) that is passedthrough the through hole 251 of the neck 26 to the first cavity 27. Thechest 31 defines some holes 311 at the flange 310 for emitting voicefrom the speaker 14 outside the human-figured toy 10.

Referring back to FIG. 1, lower limbs 50 include battery cases (notshown) for receiving batteries. The human-figured toy 10 furtherincludes sensors (not shown), for example, sound sensors or touchsensors, which are mounted at appropriate positions thereof. The controlunit in the head 20 receives instructions from the sensors, and controlsthe nose driving unit 23 to extend or retract, or the speaker 14 tooutput sound correspondingly.

Referring to FIG. 6, a curve 1 is a tested frequency response curve whenthe speaker is received in the second cavity 34 and the PCB 24 isreceived in the first cavity 27, and a curve 2 is a tested frequencyresponse curve when both the speaker and the PCB 24 are received in thesecond cavity 34. An average sound pressure level of the curve 1 is68.33 dB SPL (dB sound pressure level). An average sound pressure levelof the curve 2 is 65.74 dB SPL. Especially in the frequency rangebetween 200 Hz and 2000 Hz, which is a common sound output range of thespeaker 14, the sound pressure level of the curve 1 is always higherthan the sound pressure level of the curve 2. Thus, when the speaker 14and the PCB 24 are positioned in substantially isolated cavities, soundemitting from the toy 10 is of higher quality. Additionally, the soundcomponents comprising the toy 10 may be purchased inexpensively thusreducing manufacturing costs of the toy.

Moreover, it is to be understood that the disclosure may be embodied inother forms without departing from the spirit thereof. Thus, the presentexamples and embodiments are to be considered in all respects asillustrative and not restrictive, and the disclosure is not to belimited to the details given herein.
